The axolotl (Ambystoma mexicanum) is a unique amphibian native to the lake complex of Xochimilco near Mexico City. Despite often being referred to as a “Mexican walking fish,” it is important to clarify that axolotls are not fish but rather a type of salamander that belongs to the class of Amphibia.

Physical Characteristics

Axolotls are not only cherished for their intriguing biology and captivating appearance, but also for several distinctive physical characteristics that set them apart from other amphibians. Here are the key features that make axolotls unique:

  • External Gills: One of the most visually striking features of axolotls is their external gills, which appear as feathery protrusions on each side of their head. These gills are richly vascularized, allowing for efficient oxygen exchange directly from the water, a necessity given their fully aquatic lifestyle.
  • Neotenic Features: Unlike most amphibians, axolotls do not undergo metamorphosis to transition to a terrestrial form. This means they retain their larval features, such as the dorsal fin that runs along the length of their body from the back of the head to the tail, throughout their lives. This retention of juvenile characteristics into adulthood is known as neoteny.
  • Wide Variety of Colors: Axolotls exhibit a fascinating array of colors due to genetic variations. The most common types include the wild type, which has a mottled green and brown appearance; leucistic, which features a pale body and pink or red eyes; albino, characterized by a lack of pigment and red eyes; and melanoid, which presents a dark, almost black body. These variations make each axolotl visually unique.
  • Size and Body Structure: An adult axolotl typically measures between 9 to 12 inches (23 to 30 cm) long, though some can grow larger under optimal conditions. They have a broad, flat head and a wide body suited to their aquatic environment. Their limbs are short with long, thin digits, ideal for gliding through water rather than walking on land.
  • Lidless Eyes and Sensory Barbs: Axolotls have small, lidless eyes, which contributes to their distinctive look. While their eyesight is not particularly strong, they are aided by other sensory adaptations. For example, around their head are tiny sensory barbs, which help them detect changes in their environment, crucial for hunting prey in murky waters.
  • Tail Fin for Swimming: The tail of an axolotl, which contains a fin that extends from the body, plays a crucial role in their locomotion. The tail fin helps propel them through water with ease, allowing for graceful and efficient movement.

These physical traits not only contribute to the axolotl’s ability to survive and thrive in aquatic environments but also add to the mystique and appeal of keeping them as pets. Their unique characteristics are a window into evolutionary biology and a constant reminder of the diversity of life forms on our planet.

Axolotl Types

Axolotl Types

Axolotls come in a variety of morphs, each with unique physical characteristics and colors. Understanding these different types can help enthusiasts choose their preferred axolotl and provide proper care. Here’s a detailed overview of the most common axolotl types:

  • Wild Type: This morph has a dark, olive-green base color with gold and black speckling. It closely resembles the appearance of axolotls in their natural habitat and is the most common type found in the wild.
  • Leucistic: Often referred to as ‘pink‘ or ‘white‘ axolotls, this type has a pale pink body with red or pink eyes. It lacks pigmentation except in the eyes, making it one of the most visually striking morphs.
  • Albino: There are two types of albino axolotls—golden and white. Both lack melanin, resulting in a lack of color in their skin and eyes. Golden albinos have a yellowish tone with golden eyes, while white albinos are pure white with red eyes.
  • Melanoid: This morph exhibits a uniform dark black coloration throughout its body, with little to no iridophore pigmentation (reflective cells). Melanoids lack the shiny gold speckling typical of wild types and have a matte finish on their skin.
  • Axanthic: These axolotls are characterized by their lack of yellow pigments, giving them a grey or blue-grey appearance. They have dark eyes and are rarer than other morphs.
  • Copper: A rarer type, copper axolotls have a coppery brown color with shiny speckles. Their eyes can be light brown, yellow, or green, which distinguishes them from other morphs.
  • Chimera: One of the rarest forms, a chimera axolotl occurs due to the fusion of two embryos into one, leading to an axolotl that is literally split down the middle in terms of coloration and pattern. This type is extremely rare and not typically seen outside of specialty breeders.
  • Mosaic: Similar to chimeras, mosaic axolotls have patches of different colors and patterns across their body due to genetic variations. Each mosaic axolotl is unique, with no two having the same pattern.

Each of these axolotl types offers something special in terms of appearance and can be a delight to care for.

A: The cost of an axolotl can vary depending on the type and where you purchase it. Typically, prices range from $20 to $70 for common types, but rarer morphs like coppers or melanoids can be more expensive. Additionally, setting up and maintaining an appropriate aquarium can add to the initial cost.

Q: What does an axolotl eat?

A: Axolotls are carnivorous and prefer a diet consisting of live prey such as worms (e.g., bloodworms, earthworms), small fish, and crustaceans. They can also be fed high-quality pellets designed for carnivorous amphibians. Feeding them a varied diet helps ensure they receive all necessary nutrients.

Q: How big does an axolotl get?

A: An adult axolotl typically grows to about 9 to 12 inches (23 to 30 cm) in length, though some individuals may grow larger depending on their genetics and the quality of their care.

Q: Is it illegal to keep an axolotl as a pet?

A: The legality of keeping an axolotl as a pet depends on local laws and regulations, which can vary significantly by country and even by state or province. In some places, it is legal to keep axolotls with the proper permits, while in others, such as California, New Jersey, and Maine in the United States, it is illegal due to concerns about them becoming invasive species or due to conservation efforts. Always check local wildlife regulations before acquiring an axolotl.

Q: What is the ideal tank size for an axolotl?

A: A single axolotl should be housed in at least a 20-gallon tank. For each additional axolotl, it’s recommended to add an extra 10 gallons to ensure enough space for each individual to thrive.

Q: How often should I feed my axolotl and what is the best diet?

A: Juvenile axolotls should be fed once a day, while adults require feeding two to three times a week. A balanced diet for axolotls includes earthworms, bloodworms, and specially formulated pellets. Occasional treats can include small pieces of lean meat like chicken or beef heart.

Q: How do I maintain the water quality in my axolotl’s tank?

A: Regular water changes (about 20% per week) and a reliable filtration system are crucial. The water temperature should be maintained between 60-64°F (16-18°C), and the pH should be kept between 6.5 and 7.5. Regular testing for ammonia, nitrites, and nitrates is also essential.

Q: What are the signs of a healthy axolotl?

A: A healthy axolotl is active, has a good appetite, and shows no signs of physical distress such as lesions or discoloration. Its gills should be full and brightly colored, indicating good oxygenation and water quality.

Q: Can axolotls be housed with other pets?

A: Axolotls should not be housed with other types of fish or amphibians due to the risk of injury or disease. They can live with other axolotls if they are similar in size and the tank is sufficiently large, but care must be taken to monitor their interactions.

Q: What should I do if my axolotl looks sick?

A: If your axolotl shows signs of illness, such as lethargy, lack of appetite, or visible wounds, consult a veterinarian who specializes in exotic pets. Early diagnosis and treatment can prevent more serious health issues.

Q: What do axolotls use for shelter?

A: Axolotls prefer hiding spots and shelters that mimic their natural habitat. They use various items for shelter, such as aquatic plants that provide natural cover and a sense of security, small caves, rock formations, or commercial aquarium decorations that offer excellent hiding spots. Additionally, cut PVC pipes can serve as inexpensive and effective shelters, while turned terracotta pots create perfect hiding places. Driftwood adds a natural look and serves as both shelter and a surface for beneficial bacteria to grow. Ensuring multiple hiding spots helps reduce stress and allows axolotls to feel safe in their environment.

Q: Are axolotls good pets for beginners?

A: Axolotls can be a good choice for beginners who are willing to invest time in learning about their specific care requirements and are committed to maintaining the proper tank environment and diet.

Q: How do axolotls regenerate their body parts?

A: Axolotls have cells at their injury sites that can differentiate into different types of tissues, allowing them to regenerate limbs, tails, and even parts of their internal organs. This process is a natural part of their biology and is one of the reasons they are so fascinating to scientists.

Q: How can I contribute to axolotl conservation?

A: Educating yourself and others about axolotls, supporting habitat conservation efforts, and choosing pets from responsible breeders who participate in conservation programs are all ways to help preserve these unique creatures.

Q: What algae eaters can live with axolotls?

A: Choosing algae eaters to live with axolotls requires careful consideration. Suitable options include species that can tolerate similar water conditions and won’t pose a threat to the axolotls. Amano shrimp and certain types of snails, like Nerite and Mystery snails, are often recommended. They help control algae without bothering the axolotls. However, it’s crucial to monitor the tank closely, as axolotls may attempt to eat smaller tank mates, and any sharp shells or claws can potentially injure the axolotls. Providing ample hiding spots and a well-maintained tank can help ensure a harmonious environment.

Q: Why are axolotls endangered in the wild?

A: Axolotls are endangered due to habitat loss, pollution, and invasive species in their native habitat of Xochimilco in Mexico City. Conservation efforts are crucial to protect the remaining wild population.

Q: Are axolotls social creatures?

A: Axolotls are not particularly social creatures. In the wild, they are solitary animals that prefer to live alone, and this behavior generally extends to captivity. While they can coexist with other axolotls if provided with enough space and hiding spots, they do not seek social interactions and can sometimes become stressed or aggressive if overcrowded. It’s important to monitor their behavior and ensure they have plenty of space to avoid conflicts.

Q: What are axolotls’ predators?

A: Some common predators of axolotl include larger fish species such as carp, tilapia, and certain species of catfish. Additionally, birds like herons and waterfowl may prey on axolotls, particularly when they are young or vulnerable. In urban areas, introduced species like crayfish can also pose a threat to axolotl populations.
